Granted: 1980-01-29
Abstract: Abstract of the Disclosure There is disclosed apparatus for printing and applying pressure sensitive labels utilizing a supply roll comprising a composite web having pressure sensitive labels secured to a web of supporting material.  The apparatus comprises a print head for printing on successive labels, a delaminator for delaminating successive printed labels from the supporting web, an applicator for applying successive printed labels, a feeding mechanism engageable with the supporting web downstream of the delaminator for feeding the composite web to present partially delaminated labels to the applicator, and an arrangement for operating the print head and the feeding mechanism in sequence.  A brake mechanism is effective upon completion of the sequence for applying braking force to the composite web upstream of the delaminator to prevent the web from advancing toward the delaminator during application to a printed label by the applicator.  The brake mechanism includes cooperable parts controlled by the print head for movement into and out of braking cooperation with the composite web and one of the cooperable parts includes a rotatably mounted roll.

Abstract: IMPROVED ELECTROMECHANICAL PRESSURE TRANSDUCER                      ABSTRACT OF THE DISCLOSURE      An improved ceramic capacitive pressure sensor adaptable for use in automobiles is disclosed.  The pressure sensor comprises a thin flexible diaphragm disc having a capacitor electrode deposited on it.  A thick cylindrical base sub-strate has a top surface with a second capacitor electrode deposited thereon and the diaphragm is bonded to the top surface of the base substrate by an annular glass ring such that the first and second electrodes are separated from each other and face each other directly across an air gap.  The diaphragm, the top surface of the base substrate and the annular glass ring form an internal cavity in which a reference vacuum is stored. In response to pressure changes outside of this cavity, the diaphragm will flex and thereby change the capacitance created by the first and second electrodes. At least one channel portion is provided in the base substrate top surface which opens into the cavity storing the reference vacuum.  This improves the electrical and mechanical characteristics of the pressure sensor.  The diaphragm electrode is substantially larger than the base electrode and extends substantially over all of the central portion of the diaphragm within the glass annular ring and in this manner the electrode acts as a shield against con-ductive elements which are exterior to the internal cavity and are adjacent to the thin diaphragm.

Abstract: DEVICE FOR COUPLING A PAIR OF RODS               Abstract of the Disclosure A coupling is mounted between a valve stem of a valve and a rod of a valve actuator.  The rod includes an extension having a piston member at the end thereof which is received within a cylinder member mounted on the end of the valve stem. The extension and piston member thereof define with the cylinder member a chamber within the cylinder member.  Force can be transmitted from the rod to the stem by full insertion of the piston member within the cylinder member.  Hydraulic fluid under pressure from an accumulator secured to the cylinder member is in communication with the chamber to limit the force transmitted from the rod to the stem when the re-lative position of the rod with respect to the stem causes the piston member to be located intermediate of the cylinder mem-ber.

Abstract: ABSTRACT A method of making a stable, emulsified, liquid starch product which comprises from about 45% to about 85% edible liquid, and from about 15% to about 55% of a whole, non-starch isolated, starch bearing material emulsified with said edible liquid.  The method comprises size reducing the starch material, slurrying the size reduced material with edible liquid, hydrothermally cooking the slurried mixture, and holding said hydrothermally cooked mixture at the temperature at which it exits from the hydrothermal cooker for from one to four minutes in order to significantly increase gelatinization and maltose values. It has also been found when this is done, lactic acid levels are increased which significantly improves the product. Finally, it has been found that the product can be used as an effective grain and silage sealer, which is also nutritional.

Invention:   WIND-DRIVEN GENERATOR APPRATUS AND METHOD              OF MAKING BLADE SUPPORTS THEREFOR     Abstract of the Disclosure Wind generator apparatus employs an induction generator with a wind-driven rotor.  Connection of the induction generator to AC power lines is controlled by apparatus that compares generator rpm and line frequency. The rotor blades have a pretwisted, varying-chord inboard portion and an untwisted, constant-chord outboard portion. The blades are self-starting, operate efficiently over a range o  wind speeds with constant pitch maintained by a torsional biasing mechanism., and pitch up automatically when the normal rpm operating range is exceeded.  An im-proved blade-supporting spar of low torsional stiffness has an I-beam configuration with filament-wound flanges: A pitch damper prevents torsional oscillations while permitting the blades to pitch up readily.  The rotor, which includes a teetering hub, is free to weather-vane about the axis of a supporting tower, but a yaw damper limits angular velocity   A guy wire and gin pole arrange-ment stabiiizes the tower and permits easy raising and lowering of the tower.

Abstract: ABSTRACT     A light device for airport runways, roads or the like has at least one lamp disposed in a casing having a trans-parent, flat cover from which a well-defined light beam is emitted.  The cover has a planar external surface and a stepped internal surface.  The lamp is adapted to emit light rays impinging substantially at right angles on the stepped surface portions of the cover, so that the light rays, upon refraction at the planar external surface, are emitted at a desired small angle.  The invention is characterised by the fact that the cover consists of a plurality of inclined discs of transparent material with interface layers of a light absorbing or light reflecting nature.  These layers are parallel to each other and perpendicular to the stepped internal surface portions so that light rays impinging at oblique angles onto the surface portions will be cancelled out by absorption in the interface layers or total reflection at the planar external surface of the cover.  This effect serves further to help in forming a well-defined light beam.

Abstract: ABSTRACT OF THE DISCLOSURE   To provide a relatively compact and linear underfilled multi-faceted rotating polygon beam scanning system, there are imaging optics for bringing a input light beam to a tangentially extending line-like focus on suc-cessive facets of a rotating polygonal scanning element and for restoring the light beam reflected from the facets to a generally circular focus on an image plane. Each of the facets subtends a sufficient angle about the axis of rotation of the scanner to ensure that the input beam remains fully seated on a single facet while the reflected beam is being scanned through a desired scan angle. Furthermore, improved linearity is achieved because the scan-ning system is symmetrical in the tangential and sagittal planes at all points between the imaging optics and the polygonal scanning element.
